I didn't read all that but, at the end of the day, I've found that I get better LoA/RL coaches if I don't hire them. Occassionally, I'll re-hire one because he was assigned the season before and is pretty good. But, for the most part, there's no reason to hire LoA/RL coaches.
I hardly think it's cheating or even having a "cheating mindset". If I discovered that LH 90+ power guys hit a homer every time they faced a RH, I'd tell WifS that there's a programming flaw. If they gave me the "Thanks for the ticket. We analyze suggestions, blah, blah, blah", I'd load up on LH 90+ power guys.
Is that cheating?
